' Specification of Letters pag Application aleia a ruae, 1918. sentienticense.

Be it known that we,

bination of adjustable and foldable sup-.

porting bar; supporting braces, and tie or hanger; whereby the scaffold may be readily applied to the outside of a building and engaged with the studding thereof enabling carpenters to place any suitable support such as planks on a plurality of the brackets andto work on the outside of a building.

The invention consists of an improyed bracket scafiold comprising .a supportlng bar, two foldable supporting braces, mda' tie or hanger combined in a new and improved manner as will more fully appear hereinafter.

' In the accompanying drawings :Figure 1 is a perspective of the invention applied to the side of a building, and representing a plank broken away, supported thereby; Fig. 2, a plan view of the bracket when folded; and Fig. 3, an edge view thereof.

The bracket scaffold has a bar support 1 provided with an upwardly projecting retainer 2 at its outer end to prevent the plank or other platform from accidentally slipping from the support. [At its inner end the supporting bar 1 has a square hook 3 adapting it to engageja piece of studdlng'ln the building on which the bracket isused.

The main supporting braces 4 and 5 are pivoted at, 6 to the outer-end part of the supporting bar lt'by a rivet or bolt, and they are provided with bent' feet 7 which may have openings to receive nails driven into the building, 1f desired, or, these feet need have no openings of any kind and simply abut the building, as'the use of nails or fasteners is not necessary. The supporting braces4 and 5 are preferably of angle iron construction for the sake of strength. The supporting braces are connected rigidly by GEORGE Boitrm BERGER and JAMES R. GooDwIN, citizens of a cr0ss piece 8 which keeps them .relativel wldely separated 'at their lower parts, a fordlng a wide bearing on the side of the ,buildmg. This prevents any lateral movement ofthe scaffold. A

A'tie or) hanger 9 has bent. ends 10 re- 'c'eiv'ed in holes in the braces 4 and 5, said ends-being headed or flattened or otherwise provided with means to prevent them from coming :out. of the said holes, but at v the same time without interfering with .the pivotal connection thusprovided between the braces 4, 5 and 9. Preferably, the tie .or hanger his made bf a single piece of bent rod and the apex 11 is suliiciently broad to permlt 1t to slide readily on the bar 1 when ad ust1ng the bracket or when folding or extending-it, while at the same time &pre-' 11 venting cracking or breaking at the hen The he or hanger 9 transmits directly to the supporting braces 4 and 5 any weight im posed upon either side of the supporting bar 1, thus preventing any twisting motion which would result in the walking of the feet 7 on the wall of the building.

The scadold is shownin position for use number of scafloldbrackets may be packed into. very compact form for shipping par. poses and they can be readily separated" and opened out at the point. of use.

-. The bar 1, main braces, 4, 5, and tie-er in Fig. 1 and in folded condition in Figs. 2 and 3. Being adapted for folding sub stantially flat, as shown in Figs. 2' and .3. a

hanger 9 can be adjusted'in relation to each.

other, according to the position of the bracket onthe building, soasto' locate the plank supporting bar 1 as may be desired by the carpenter or other artisan. The comhi= nation of the bar fl. the main and supporting braces i, 5., and tieor hanger 9 afiords great rigidity and-strength. ltl'aving thus described our invention, what we cla m as new and desire to-secure by Lette s Patent. is:- Y

An all-metal fo dable bracket scafiold com rising the combination of a single supporting bar having a hoolrat its inner end ada ted to engage the building. a main supporting brace composed of connected memhers. convergingand pivoted 'to the outer part of the sup orting bar and foldable in relation-to said supporting bar alongside the latter, the. other ends ,of the suppotting roe members being adapted]. to rest against the building, and a one-piece inverted V-shape tie or hanger Whose apex straddles, resti upon, and is slidable anti foldahle on, the 5 supporting bar and Whose enoi parts are pivoted to the free end parts of the respective members constituting the main supporting brace, in such a way that When Weight is imposed on one sinie of the sup- 1c porting hnr such Weight is transmitted directly to the inner endl of the supporting brace on that side of thehnr, thus preventing all twisting motion. In testimony whereof, We hereunto our signatures in presence of two witnesses. 15
